      Description

      Currently IMAGE_BOOTLOADER_FILE assumes a single binary for the boot loader but it's possible to have SPL and even TPL modes in U-Boot that will require multiple files.

      Note that Yocto currently has an SPL_BINARY variable that is used when SPL is needed but doesn't seem to directly support TPL.

      The current proposal is to use something similar to 'IMAGE_BOOTLOADER_FILE = "SPL;1 u-boot.bin;69"'

      See https://github.com/mendersoftware/meta-mender/pull/494 and https://groups.google.com/a/lists.mender.io/forum/#!searchin/mender/mirza$20krak/mender/hyHk9a6C4K8/A23cC8qLBAAJ for more context.

      Note, ideally we would rename the variable to IMAGE_BOOTLOADER_FILES but that may be a more invasive change.
